Hello. I had a headache that lasted about 1 week. It was at the lower back of my head and at times there was pain in my neck as well. I have had a really stiff back, neck, and shoulders for some time now. So, I thought it was maybe a tension headache I was having, though it was the first time ever having one. The headache was more of a dull pressure that occasionally came and went. Sometimes I would feel light headed and today I feel like I'll fall asleep any moment
